This article is an attempt to teach the tricks that unlock the power of the jeweler's refractometer. What is refractive index (RI)? Refractive index is a measure of the optical density of a material. Webmum retardation. It’s interference figure should be a nearly centered optic axis figure. The optic sign may be determined from the optic axis figure by inserting the quartz accessory plate when the centered isogyre is concave to the NE. If there is addition to the retardation in the NE (constructive interference), the mineral is positive.
